【摘要】 为了获得更好的激光雷达图像融合效果,提高图像融合质量,提出一种基于小波变换的激光雷达图像融合方法。首先采用小波变换对激光雷达图像进行分解,得到不同频率的小波系数,然后对低频小波系数进行加权,选择高频小波系数实现激光雷达图像融合,最后采用仿真实验对其性能进行分析。结果表明,相对于当前经典激光雷达图像融合方法,本文方法的激光雷达图像融合结果的主观和客观质量均更优,完全可以满足激光雷达图像实际应用的需求,具有较高的实际应用价值。更多还原

【Abstract】 In order to obtain a better effect of laser radar image fusion and accelerate the speed of laser radar image fusion,this paper proposes a laser radar image fusion technology based on wavelet transform. firstly,wavelet transform is adopted to laser radar image decomposition,and the wavelet coefficients in different frequency,secondly,weight the low-frequency wavelet coefficients and the larger wavelet coefficients to achieve laser radar image fusion,finally simulation experiments is used to test the performance. The results show that,compared to the current popular laser radar image fusion method,the proposed method for laser radar map image fusion results of subjective and objective quality are better,can fully meet the practical application of laser radar image,and has high practical application value.更多还原
